During the period from March 1978 to November 1979, 232 consecutive patients with traumatic hyphaema were allocated by admission-date to conservative treatment and to treatment with the antifibrinolytic drug tranexamic acid. Secondary haemorrhage occurred in only two of 102 tranexamic acid treated patients, while secondary haemorrhage occurred in 12 out of 130 conservatively treated patients. This difference was statistically significant. Some clinical aspects of the rebleeding cases are presented and briefly discussed.

Premedication with diazepam 0.25 mg kg-1 by mouth was compared with placebo in a double-blind trial in patients undergoing day-case surgery under general anaesthesia. Diazepam decreased significantly preoperative discomfort and apprehension. The patients were discharged on time regardless of the type of premedication, and complaints at the time of discharge and on the following day could be related only to the length of anaesthesia and not to the type of premedication. Premedication given early in the morning remained effective for up to 6 h.
